Core Viewpoint - The "Jimu No.1" airship, developed by the Chinese Academy of Sciences, has successfully completed a month-long atmospheric observation mission in the Tibet region, demonstrating significant advancements in technology and data collection capabilities for studying the "Asian Water Tower" [2][5][7]. Group 1: Development and Technology - The airship, also known as a tethered balloon, utilizes helium for lift and is designed to function as a mobile laboratory for aerial scientific experiments [3]. - The "Jimu No.1" has achieved a high level of domestic technology localization, enabling it to withstand extreme conditions such as cold temperatures, strong winds, and low pressure found in the Tibetan Plateau [4]. - Over the past five years, more than 60 patents related to airship technology have been filed, contributing to technological independence and innovation in the field [4]. Group 2: Research and Data Collection - The airship's mission aims to quantify the spatial and temporal distribution of water vapor in the Tibetan Plateau, which is crucial for understanding the dynamics of the "Asian Water Tower" [7]. - During its recent tests, the airship reached an altitude of 5,900 meters and successfully captured critical data on atmospheric composition, pollutant distribution, and cloud microphysical parameters [7]. - The data collected will be used to develop global atmospheric transport models, providing a solid foundation for further research on the "Asian Water Tower" [7]. Group 3: Future Applications and Collaboration - The airship is positioned as an open aerial testing platform, inviting collaboration with other scientific instruments to enhance research capabilities [8]. - The team has planned various new tasks for the airship, including monitoring grassland conditions and addressing communication challenges in remote marine areas [8]. - The unique advantages of airships, such as pollution-free operation and the ability to remain at any altitude without additional power, are being leveraged to expand their application in scientific research and public service [8].
